Storytelling in PowerPoint - New reset behavior
When integrating a report into your presentation, it is important to ensure that it remains stable and unaltered. The add-in refreshes data from Power BI without modifying the report definition.
However, since Power BI reports are dynamic, sometimes you may want PowerPoint to get the latest changes done in the report in Power BI service. Previously, you had to remove and re-embed the report to achieve this. Now, with the improved ‘Reset’ command, you can choose either to reset the add-in to its original state as initially added to the presentation or to reset and update it with the current view from Power BI.
Description automatically generated">
Storytelling in PowerPoint - Supporting page up & down
You can now use the Page Down/Up keys on your keyboard to quickly navigate between slides when using the Power BI add-in. This is especially useful when the add-in captures the entire slide, and you want to advance the slide rather than trigger a Power BI event.

Enhancement to Text slicer (preview)
Following the November 2024 Text slicer release, this update enhances functionality and user experience by allowing multiple text selections.
The Text slicer is currently in preview. To enable the Text slicer, go to Options and settings > Options > Preview features > Text slicer visual to make sure it is selected, then restart Power BI.
This month’s enhancement adds a new Slicer settings control with an on/off toggle allowing the slicer to Accept multiple values. All other existing formatting options for the Input text, Apply button, and Input text box from our November update remain the same in the Format pane.
After creating a Text slicer visual and adding a text field from the data model, users can filter the dataset based on user input. Simply select the slicer input box, type your text, and apply the filter either by selecting the apply icon, pressing enter, or selecting outside the visual. The slicer immediately filters and displays the results, and you can repeat these steps to add more text selections.
When the Accept multiple values option is enabled, additional text can be added to the slicer by repeating these steps, thereby allowing multiple selections for filtering the dataset. Keep in mind that switching the toggle on or off will clear any previous text selections.

Enhancements to Treemap visual
This month's update includes significant enhancements to the Treemap visual, with three new tiling methods that improve layout options, plus new spacing controls to enhance the visual's appearance and usability. These features offer richer control and customization, resulting in more precise and aesthetically pleasing treemaps in Power BI.
Treemap visuals are powerful tools for data visualization that allow users to represent hierarchical data through nested rectangles. Each branch of the hierarchy is represented by a rectangle, which is then tiled with smaller rectangles representing sub-branches. This structure allows for quick comparison of different category proportions.
To generate two-level Treemap visuals, ensure that both the Category and Details fields are enabled. This allows you to visualize the hierarchical relationships between various categories and their subcategories in a clear and organized manner.
Three new Tiling methods:
Squarified: This method uses a squarified treemap algorithm to prevent elongated rectangles, creating a balanced layout. It arranges rectangles so their aspect ratios are close to squares, making size comparisons potentially easier.
AI-generated content may be incorrect.">
Binary: This method continuously divides the chart area into two sections while incrementally adding new rectangles/nodes creating a balanced and visually appealing treemap. Each hierarchy level further splits the space, resulting in an organized treemap that adapts to the dataset's structure. It may produce different visual characteristics compared to squarified algorithm depending on the dataset.
AI-generated content may be incorrect.">
Alternating (Columns, Rows): The Alternating method clearly distinguishes categories by first splitting them by columns and then within each column by rows. This method effectively organizes datasets with numerous hierarchical levels.
AI-generated content may be incorrect.">
This month's update also introduces new spacing options to enhance the readability and appearance of the Treemap visual:
- Space between all nodes: This setting introduces gaps between adjacent nodes at all hierarchy levels, reducing clutter and improving clarity.
- Space between groups: By adding extra space around each node group, this option visually separates different hierarchical groups, which helps to visually distinguish categories within the hierarchy.

Folder support in Git
Timeline update - Folder support is planned to roll out to all customers by mid-April. Thank you for your patience!
This update ensures that the folder structure in your Fabric workspace is seamlessly mirrored in your connected Git branch, providing an organized and consistent experience across both platforms.
Description automatically generated">
New features:
- Folder Structure Mirroring: The entire folder hierarchy in Fabric is reflected in Git and vice versa, enabling a more intuitive and organized collaboration process.
- Nested Folders Are Synced: Fabric items located within nested folders will now be included in the sync, and their folder structure will be preserved.
- Item Updates as Commits: Changes to an item's folder (e.g., moving an item to another folder or reorganizing folders) will now appear as updates or commits in Fabric.
Subfolder support is enabled by default as soon as the feature is live. This means any folder differences between Fabric and Git will automatically show up as updates or commits.
Handling Folder Changes Safely
If changes to the connected branch cannot be made directly due to branch policy or permissions, we recommend using the ‘Checkout Branch’ option.
Guidelines for managing this:
- Checkout a New Branch: Use the checkout branch feature to create a branch with the updated state of your Fabric workspace.
- Commit Folder Changes: Any workspace folder changes can then be committed to this new branch.
- Merge Changes: Use your regular pull request (PR) and merge processes to integrate these updates back into the original branch.
OneLake
OneLake Catalog - Semantic model table & column description
We are expanding the details view of Semantic Models, to also include table and column descriptions which were set in the data model editor in the service or in Power BI Desktop. The goal is to provide consumers with multiple trust signals regarding an artifact, thereby enabling them to make swift and well-informed decisions.
This improvement provides additional name and type details for tables and columns in semantic models, helping data consumers identify relevant tables more efficiently and encouraging data producers to document organizational knowledge. We are planning to expand this ability to other data items in the future.
Filtering workspaces in OneLake Catalog
You now have a dedicated filter for workspace names, which will allow you to quickly locate the required workspace. This makes it easier for users with access to multiple workspaces, and makes finding the relevant workspace difficult if it isn't featured at the top of the list.

Native Execution Engine on Runtime 1.3: simplified enablement and transition from Runtime 1.2
Introducing a new update that simplifies enabling the Native Execution Engine. Now, activating it is as easy as toggling a switch! You’ll find the new toggle button in the Acceleration tab within your environment settings.
If you were previously using the Native Execution Engine, please navigate to the Acceleration tab and re-enable it using the new toggle. This updated UI control now takes precedence over any previous configurations in Spark settings, meaning prior setups will remain inactive until re-enabled with the toggle.
Additionally, the Native Execution Engine now fully supports our latest runtime version, Runtime 1.3 (Apache Spark 3.5, Delta Lake 3.2). As a result, support for Native Execution Engine on Runtime 1.2 is ending. We recommend upgrading to Runtime 1.3 to maintain support, as native acceleration will soon be unavailable on Runtime 1.2.
Legacy timestamp support in Native Execution Engine on Runtime 1.3
The latest Native Execution Engine on Fabric Runtime 1.3 introduces legacy timestamp handling, ensuring compatibility across Spark versions. This feature addresses timestamp issues caused by Spark 3.0’s shift to the Java 8 date/time API (Proleptic Gregorian calendar) from the previous hybrid Julian-Gregorian calendar.
With the configuration spark.gluten.legacy.timestamp.rebase.enabled, the Native Execution Engine auto-adjusts for calendar differences in Parquet files and Delta Tables, handling dates seamlessly across Spark versions. Dates post-1970 are unaffected, ensuring consistency without extra steps.
To activate this feature, add the following to your Spark session:
SET spark.gluten.legacy.timestamp.rebase.enabled = true;
Notebook and Spark Job definition execution with service principal
The service principal support for Fabric API was announced back in September. Today, we unblock another key scenario, enabling run the Notebook/Spark Job Definition execution under SP (service principal) for Data Engineering experience.
Using the Fabric Job Scheduler API, users can trigger the execution of either a Notebook or Spark Job Definition (SJD) and monitor its execution status. By utilizing the same API with a service principal's access token, the Spark Job associated with the notebook/SJD will run within the security context of that service principal.
This update enhances SP support for the Data Engineering experience, expanding its capabilities beyond current CRUD operations to include comprehensive job execution coverage. To make sure the SP does have the privilege to run the job, you need to add that SP as Admin/Contributor/Member into the workspace which hosts the Notebook/SJD.
If the notebook/SJD has some code related with Data Science scenario such as Model/Experiment, the SP triggered execution could fail, this is something we are working on to unblock them later.
Lineage Enhancement to Spark Notebook
A new improvement to the lineage related to Spark Notebooks has been introduced to enhance data exploration effectiveness. You can now view all Lakehouses connected to your notebook, including pinned and additional Lakehouses.
This update helps you:
- Perform Impact Analysis: Easily assess how changes affect data workflows by identifying which Lakehouses are being used.
- Document Data Pathways: Streamline collaboration and audits with clear visibility into data relationships.
Experience smarter data management today with this lineage enhancement to your Spark Notebooks!
Data Warehouse
COPY INTO column count check
The COPY statement offers flexible, high-throughput data ingestion from an external Azure storage account into Fabric Data Warehouse tables. When there is a column count mismatch between rows in source files and the target table, COPY INTO has the following behavior:
- If a row within the source files has less columns than the target table, COPY INTO inserts columns with missing values as NULL. If there’s no corresponding value for a non-nullable column in the source data, then COPY INTO fails.
- If a row within the source files has more columns than the target table, any excess columns from source files are ignored in the target table.
We’re introducing a new option for COPY INTO that allows you to control the behavior of your data ingestion jobs by checking if the count of columns in the source data matches the count of columns on your target table.
The following syntax should be used for the column count check option:
COPY INTO FactSale FROM '<external_location>'
WITH (
FILE_TYPE = 'CSV',
[ , MATCH_COLUMN_COUNT = { 'ON' | 'OFF’ } ]
)
MATCH_COLUMN_COUNT checks the column count on each row of each source file for a match against the target table specified in the COPY INTO statement. This option is available only for CSV file type sources now, with support for Parquet coming soon. The default behavior of COPY INTO remains unchanged and is equivalent to using MATCH_COLUMN_COUNT = ‘OFF’.
Learn more about COPY INTO and this new option, refer to the documentation.
Enhancing COPY INTO operations with Granular Permissions in Data Warehouse
One of the challenges our customers shared is that executing COPY INTO command requires users to have at least the Contributor role at the workspace level, granting broad permissions that may exceed what is necessary for specific tasks.
We are excited to announce that now a user with minimum ‘read’ permissions on the control plane will be allowed to execute write operations at the Data Warehouse level.
The benefits of this change include reducing the need for broad workspace roles, and it also works seamlessly even when storage account is protected behind a firewall.
Learn more about COPY INTO in our documentation and to know more about this new option, check out this blog post COPY INTO support for secure storage with granular permissions.
Introducing default schema changes in Data Warehouse
We are happy to announce the ability to change the default schema in Fabric Data Warehouse. With this improvement, which has been highly requested by our customers, we strive to make database management and enhanced security more straightforward. This is done using the ALTER USER statement, ensuring that every user has a predefined schema context when they connect to the database.
| ALTER USER [username] WITH DEFAULT_SCHEMA = [schema_name]; |
By allowing administrators to assign default schemas to users, we ensure that users operate within their designated schemas, reducing the risk of unauthorized access and simplifying permissions management.
For more information, check our documentation:
Enhanced performance metrics in Query Insights
New features have been introduced to provide deeper insights into query performance. With the introduction of Data Scanned Analysis, you can now determine if large data scans are contributing to slower query execution. This feature allows you to compare similar queries, pinpoint fluctuations caused by changes in data scanned, and even identify when cache was utilized.
Additionally, we've introduced allocated CPU time as a key performance metric. This enables you to understand the resources consumed by your queries and workloads. High CPU time often correlates with higher costs, making it easier to identify and address resource-intensive queries. These enhancements empower you to optimize performance and manage costs effectively.
These columns are available in queryinsights.exec_requests_history:
| Column name | Data type | Description |
| allocated_cpu_time_ms | Bigint | Shows the total time of CPU(s) that was allocated for a query’s execution. |
| data_scanned_remote_storage_mb | Bigint | Shows how much data was scanned/read from remote storage (One Lake). |
| data_scanned_memory_mb | Bigint | Shows how much data was scanned from local memory. Data scanned from disk and memory together indicates how much data was read from cache. |
| data_scanned_disk_mb | Bigint | Shows how much data was scanned/read from local disk. Data scanned from disk and memory together indicates how much data was read from cache. |
For more information, check out our documentation:
Previewing estimated Query Plan available via SHOWPLAN_XML
The Preview for SHOWPLAN_XML in Microsoft Fabric Data Warehouse is now available. This capability allows users to generate and view the estimated query execution plan in XML format, a tool for analyzing and optimizing SQL queries. Whether you're troubleshooting performance bottlenecks or refining query strategies during development, SHOWPLAN_XML offers a granular, detailed view of how the database engine plans to execute your queries. By providing insights into operations like joins, data movements, etc. it helps pinpoint inefficiencies and identify opportunities to enhance performance.
How can you use SHOWPLAN_XML?
- Enabling SHOWPLAN_XML - To enable SHOWPLAN_XML, execute the following SQL command: SET SHOWPLAN_XML ON;This command instructs Fabric DW to return execution plans in XML format for all subsequent queries.
- Running Queries - After enabling SHOWPLAN_XML, run the queries that you wish to analyze.The execution plan for this query will be returned in XML format.
- Capturing the Output - Capture the SHOWPLAN_XML output by saving the result set to a file or copying it to an XML viewer. Ensure that the entire XML content is preserved for accurate analysis.
- When running SHOWPLAN_XML in Fabric UI, copy results and save them as a .sqlplan file. Open this file in SSMS to view the graphical plan.
Description automatically generated">
- If you run in SSMS, use the SET SHOWPLAN_XML syntax as explained above. You can also use the plan Display Estimated Plan button to see the graph.
Description automatically generated">
- Turn OFF SHOWPLAN_XML - Run SET SHOWPLAN_XML OFF to receive results instead of the execution plan when you run queries.
For more details, check out our documentation:
Query Hints in Fabric Data Warehouse
Along with SHOWPLAN_XML, we are announcing support for some query hints. Query hints in Fabric SQL are optional keywords that can be added to SQL statements to provide additional information or instructions to the query optimizer. These hints can improve the performance, scalability, or consistency of queries by overriding the default behavior of the query optimizer.
To use a query hint, the OPTION clause is added at the end of the query, followed by the name of the query hint and its optional parameters in parentheses. For instance, if you want to instruct the query optimizer to use a hash-based algorithm for the GROUP BY operation, you can use the HASH GROUP query hint.
SELECT band_id, SUM(ticket_cost)
FROM gigs
GROUP BY band_id
OPTION (HASH GROUP)
Fabric SQL supports a variety of query hints, including HASH GROUP, ORDER GROUP, MERGE UNION, HASH UNION, CONCAT UNION, FORCE ORDER, LOOP JOIN, HASH JOIN and REPLICATE. Each of these hints serves a specific purpose, such as improving the performance of GROUP BY operations, UNION operations, or join operations. However, query hints should be used with caution and tested thoroughly, as they can have negative effects on the performance, scalability, or consistency of queries if used incorrectly or unnecessarily. It is essential to monitor and evaluate the impact of query hints on queries and adjust them as needed.

Simplifying search & introducing Filter in Object Explorer
The search and filter features in Fabric Data Warehouse empower users to efficiently navigate and manage their data.
The new search feature is designed for ease of discovery and intuitive use, allowing users to locate objects in the object explorer by entering keywords. The search function quickly highlights matching objects and highlights the results within the object explorer for the user.
The filtering feature in Object Explorer is an essential tool for managing large data warehouses and simplifying navigation within your warehouse environment. When dealing with numerous objects, such as schemas, tables, or stored procedures, finding specific items can be challenging. The filtering capability allows you to streamline this process effectively.
The filtering options allow for precise object selection based on various criteria such as object type, created date, last updated, enabling you to focus on the most relevant information for your exploration in object explorer.
By leveraging this combination, users can significantly reduce the time spent searching or filtering data, allowing for more focus on troubleshooting, generating scripts for development and documenting objects in Object Explorer.
Open from SSMS & VS Code
Developers now can easily access their Fabric Warehouse through their preferred client tools. With a renewed focus on integrating with widely used developer tools, this enhancement prioritizes flexibility and convenience, enabling seamless connections with SQL Server Management Studio and Visual Studio Code.
This means you can dive right into your data analysis and management without any hassle, using the tools you know and love.
Developers have the option to open Fabric Warehouse in SQL Server Management Studio (SSMS) or Visual Studio Code, either from a workspace or within the warehouse itself.
You can open the warehouse in VS Code or by downloading VS Code.
Note that Visual Studio code will install ms-sql for you and pre-populate Server and Database name in the connection to get started.
You can also open or download SSMS to begin using your preferred tool.
Git Status Bar to Fabric Warehouse Artifact
The Git artifact status bar offers a comparable experience to the status bar in the workspace.
When accessing the DW item page, you can view the details of the connection between the workspace and the Git repository, such as:
- The name of the branch to which the workspace is connected
- The time of the last sync event between the workspace and the repository
- A hyperlink to the most recent commit on the branch.
The Git status bar is useful for following scenarios
- It offers a user-friendly interface for developers, like that of Visual Studio Code and other applications that display the status of the connection to the remote repository at the artifact level.
- More features, such as the ability to commit directly from the artifact page, will be added soon.
Tooltip support for built-in functions
Fabric Web editor provides robust tooltip support for built-in functions, enhancing the development experience by offering quick access to function details. When you hover over a built-in function in your query, web editor displays an interactive tooltip. This tooltip includes the function’s name, possible parameters, and a brief description. For example, if you hover over the COUNT() function, the tooltip will show its syntax and a short description of what the function does.
This feature is particularly useful for quickly referencing function parameters and understanding their usage without leaving the query window. It helps streamline the coding process and reduces the need to manually look up function details.
Stay updated with IntelliSense
Our goal is to facilitate Fabric developers in writing queries by enabling new T-SQL statements in Fabric Warehouse. Recently, we have integrated IntelliSense support for the following newly released features.
- FOR JSON - Announcing improved JSON support in Fabric DW
- COPY INTO – Column count check: COPY INTO (Transact-SQL) - Azure Synapse Analytics and Microsoft Fabric
JSON aggregates (Preview)
As part of our ongoing enhancements to JSON functionalities in Fabric DW, we are excited to announce the preview of two new JSON aggregate functions:
These aggregate functions simplify the process of concatenating columns within a GROUP BY operation and formatting them as JSON text.
Description automatically generated">
Previously, achieving this required the use of the generic STRING_AGG() aggregate combined with manually concatenated and escaped column values to produce a valid JSON string. Now, with JSON_OBJECTAGG and JSON_ARRAYAGG, this process is streamlined and more efficient.
These functions are already in public preview in Azure SQL Database and Azure SQL Managed Instance, and Fabric DW is now joining this preview. They will become generally available across all SQL flavors simultaneously.
Spatial analytic functions
Spatial analytics functions are now fully supported in Fabric DW and SQL endpoints. Spatial functions enable you to perform complex calculations on the geographical and geometrical shapes, such as determining the distance between points, checking whether a point is within a polygon, or whether the shapes intersect. Previously, these functions were not fully supported. Comprehensive support commenced in December 2024.
Fabric DW supports both geography objects and functions for simple 2D geometries, as well as geography objects for more realistic shapes represented on the Earth's surface. This includes all spatial reference systems available in SQL Server and Azure SQL databases.
While Fabric DW does not support storing spatial types directly, you can represent your spatial objects as float columns representing the (latitude, longitude) pairs or store complex shapes in VARBINARY columns in Well-Known Binary (WKB) format. You can then use spatial functions to convert them to spatial objects and apply spatial operations.
For example, the following query finds the number of trips starting near the Empire State Building in New York (40.748817, -73.985428):
Description automatically generated">
Be aware that the spatial functions are among the most complex calculations you can perform in your DW, which might impact performance. To improve the query performance, ensure you are physically storing a geoindex column that can approximately determine the location of an object or shape (e.g., using a bounding box, quadkey, H3 index, geohash, or something similar) and prefilter data based on this index column instead of applying a direct spatial filter. Since spatial filters and joins are the most resource-consuming operations, they might impact performance if rely only on them without additional indexing columns.
Once you reduce your data set using geo index columns, you can perform complex spatial analytics using geography and geometry methods.
SQL analytics endpoint performance improvement
We released an update to the SQL analytics endpoint that improves query performance and data freshness. Previously you might have encountered slow SELECT statements and stale data in your tables. With this update, metadata changes are synced more efficiently to the SQL analytics endpoint, resulting in faster SELECT query execution and data updates. This improvement ensures a more responsive and reliable experience for our users.
We'll continue to enhance the SQL analytics endpoint based on your feedback, so make sure to comment or vote on Ideas.
Databases
Tenant Level Private Link (Preview)
We are excited to announce the preview of Tenant Level Private Link for SQL database in Fabric! This new feature enhances the security and privacy of your data by allowing you to connect to your SQL database through a private endpoint within your virtual network. With Private Link, you can now ensure that your data traffic remains within the Microsoft network, reducing exposure to the public internet and minimizing potential security risks. This integration simplifies network architecture and provides seamless and secure connection experience for your SQL database in Fabric.

Real-time Intelligence
Override late arrival tolerance in Activator
Late arrival tolerance refers to how long Activator waits for an event to arrive and be acknowledged and processed. This setting ensures that late events and events that arrive out of order have an opportunity to be included in the rule evaluation. The consideration is to tradeoff on getting more ‘accurate’ rule evaluations by waiting longer for late data points to arrive or run your rule on potentially incomplete data, so the rule is activated sooner.
The default setting is 2 min, but now you can set the late arrival tolerance to a longer or shorter period.
Please note that this setting will not be shown for rules that are built on Power BI or KQL data.
Create new Activator items
As of November 2024, Real-time Intelligence and Activator are now Generally Available (GA)! You may need to work with your admin to ensure that you have all the capabilities available to you in Activator GA.
If your tenant is using the preview version of Data Activator but does not have Fabric enabled, you will no longer be able to create new Activator items. To keep using Activator and create new Activator items, enable Fabric for your tenant.
To enable Fabric, go to the admin portal and make sure that users are allowed to create Fabric items.
Please note that if you have delegated settings to other admins, you should also allow capacity admins to enable/disable.
RTI ALM & APIs GA
Application Lifecycle Management (ALM) and Fabric REST APIs are now available for all RTI items: Eventstream, Eventhouse, KQL Database, Realtime dashboard, Query set and Data Activator.
ALM includes both deployment pipelines and Git integration, both allow you to manage change within your workspaces. This enables multiple scenarios, from simply ‘recording’ changes in Git to have an audit trail, to deploying your development workspace, with all its dependencies to a staging and production workspace, to introducing changes via feature branch connected to feature workspace.
REST APIs enables more control over changes by allowing you to programmatically create / read / update / delete (CRUD) your artifacts.
Data Factory
Mirroring
Mirroring now supports replicating source schemas
Mirroring in Fabric now supports replicating source schemas. When data is mirrored from various types of sources, your source schema hierarchy is preserved in the mirrored database. This ensures that your data remains consistently organized across different services, allowing you to consume it using the same logic in SQL analytics endpoint, Spark Notebooks, semantic models, and other references to the data.
The existing mirrored databases remain unchanged to maintain backward compatibility and avoid affecting downstream workload. If you want to reorganize your tables with schemas, please recreate the mirrored database.
Please refer to schema support with Mirroring in Microsoft Fabric.
Delta column mapping support for Mirroring is now available
Mirroring in Fabric now supports Delta column mapping. Column mapping is a feature of Delta tables that allows users to include spaces and special characters such as ',;{}()\n\t=.' in the table's column names. With this new capability in mirroring, columns containing spaces or special characters in names can now be replicated from your source databases to the mirrored databases.
For tables with special characters in column names that are already under replication, you can update the mirrored database settings by removing and re-adding them to include those columns.
To learn more, refer to Delta column mapping support with Mirroring in Microsoft Fabric.
Mirroring now supports CI/CD (Preview)
Mirroring in Fabric now supports CI/CD capabilities, enhancing the efficiency and reliability of your development workflows. Users can integrate Git for source control and utilize ALM Deployment Pipelines, streamlining the deployment process and ensuring seamless updates to mirrored databases. To learn more about these new capabilities, refer to CI/CD for mirrored databases in Fabric (Preview).
